CONCENTRATING-TABLE.

Specification 0! Letters Patent. Patent d N 30 1920 Application filedFebruary 19, 1920. Serial No. 359,993.

T 0 all whom it may concern:

Be it known that I, IRVING KLINDT, a citizen of the United States,residing at Round Mountain, in the county of Nye and State of Nevada,have invented a new and useful Concentrating-Table, of which thefollowin is a specification.

My invention relates to concentrating machines and is more particularlydirected to the type of machines known as wet concentrators and whichare especially adaptable for the treatment of ore pulps and slimes.

The object of the invention is to provide a horizontal concentratingtable of shallow box form and to longitudinally reciprocate the table tocause'a stratification of the pulp and the discharge of the tailings ina plane transverse to the direction of reciprocation.

Another'object is to provide a concentrating table combined with meansfor feeding the ore pulp along the longitudinal center of the table anddirecting it transversely to r the direction of reciprocation of thetable, the longitudinal reciprocation of the table causing the heaviermineral values to form a lower strata on the table surface where theydischarge into a longitudinal concentrate trough in the center of thetable surface, and causing-the lighter tailings to be discharged overthe side boards of the table in a direction transverse to the directionof reciprocation of. the table. 7

A further object is to provide a concentrating table reciprocated in asubstantially horizontal plane and in which the pulp bed is continuouslymaintained in a level plane, said table having a concentrate slot ortrough extending in a plane parallel to the direction of reciprocation.

Another object is to provide a c0ncentrating table in which the pulp bedis maintained in a level plane and the pulp is fed along thelongitudinal center of the table and parallel to its direction ofreciprocation, and is directed transversely beneath the surface of thepulp bed. 7

Various other objects and advantages will be more fully apparent fromthe following description of the accompanying drawings, which form apart of this disclosure, and which illustrate apreferred form ofembodiment of the invention.

Of the drawings:

Figure 1 is a side elevation of my improved concentrator.

Fig. 2 is a top plan view.

Fig. 3 is a top plan view with the feed trough removed.

F 4 is a longitudinalvertical section.

F g. 5 is an end elevation.

1g. 6 -is an enlarged transverse section illustrating the separation ofthe ore pulp.

In the drawings, A designates the concentrator table which is supportedupon vertical legs 13, the legs being attached to the under surface ofthe table and to the base 1 of the machine, by angled brackets 2. Thelegs are formed of flexible metal or wood to permit a relatively slightlongitudinal reciprocation of the table and at the same time aretransversely rigid to prevent any side motion thereof.

The table. A is given a reciprocating movement, longitudinally, by anysuitable operating' mechanism, such as, by means of an eccentric linkdevice, as indicated at 3.

The table is of shallow box form having a table surface a which issubstantially level, longitudinally, and which is slightly inclineddownwardly and inwardly to a medial concentrate slot 5 which extendsparallel to the direction of table reciprocation. Discharge spigot-s 6,by which the discharge of the concentrate from the slot is regulated,communicate with the concentrate slot and are adapted to discharge theconcentrate into a stationary concentrate launder C which is supportedbeneath and in longitudinal alinement with the spigots, and is slightlyinclined to direct the flow oi the concentrate toward one end of themachine. 7

The side boards 7-8 of the table A extend upwardlya distancecommensurate to the depth to which it is desired to maintain the pulpbed. The end boards 9, 10 extend upwardly to a greater height than theside boards and the adjacent portions of the side boards are inclinedupwardly to the height of the end boards, as indicated at 11, 11. Thisprovides a table having higher marginalwalls at its opposed ends, andthe purpose of this structure is to prevent the ore pulp being thrown orwashed over the table ends by the sudden changes in table movements.Each of the side boards 7, S extend below the bottom of the table andinto stationary tailings launders D.D which are slightly inclined in adirection in which it is desired that the tailings shall be discharged.

.The feed trough E is longitudinally extended the length of theconcentrator table,

the table.

above the concentrate slot 5, and rests upon and is attached to the endboards 9l0 or the trough, as by means of bolts 13, and suiti 'ablyspaced front the trough are opposed baflie plates l4l4-which extendlongitudlnally the full length of the table and vertically above thedischarge orifices 12-l2 and downwardly below the horizontal level ofthe pulp bed'on the table and below the tops ofthe table side boards7-8.

It-will be evident from the above, that the feed trough E and the tableA, and con- 'nected-parts, will be reciprocated as a unit in alongitudinal direction and in a sub stantia-lly level plane.

In operation, the ore pulp or slime will flow through the'dischargeorifices 12-42 and against-the baffle plates 14t1l which will direct thepulp downwardly beneath the surface-of the pulp bed on the table, asindicated bythe arrows 15- -15 in Fig. 6. This flow of the pulp isassisted by the reciprocation of the table which also serves to maintainthe pulpin the teed trough in an agi tated state to. prevent aseparation in said trough and to'prevent a clogging of. the dischargeorifices 12 12.

The reciprocation of the table causes a stratification of thepulp bed,the heavier mineral'values sinking tothe table surface,

I as indicated by the arrows '16-l6 and gradually working into theconcentrate slot '5',- and the lighter gangue flowing transverselyacross the table and overflowing over the table side boards 7-8 and intothe tailings launders D-D as indicated by the arrows 17-17 in Fig. 6.

I The spigots 6 may be regulated to continuously discharge theconcentrate into the V pulp-anda continuousseparation by which themineral values seek the longitudinal eenter of'the table and thegangueis directed transversely relative to the direction ofrecip-rocation and overflows the 'side boards ofthetable.
